expand (y=2,x-3)(y=2x^2+5x+6)

expand

(y = 2, x - 3) (y = 2 x^{2} + 5 x + 6)

y = 2 x^{2} - 15 x - 18

Solution steps

(y = 2, x - 3) (y = 2 x^{2} + 5 x + 6)

= (2 =, y x - 3) (2 = y x^{2} + 5 x + 6)

Distribute parentheses

y = 2, x y = 2 x^{2} + y = 2, x \cdot 5 x + y = 2, x \cdot 6 + (- 3) y = 2 x^{2} + (- 3) \cdot 5 x + (- 3) \cdot 6

Apply minus-plus rules

+ (- a) = - a

y = 2, y x = 2 x^{2} + y = 2, 5 xx + y = 2, 6 x - 3 y = 2 x^{2} - 3 \cdot 5 x - 3 \cdot 6

Expand

2 x^{2} - 3 \cdot 5 x - 3 \cdot 6 : 2 x^{2} - 15 x - 18

y = 2 x^{2} - 15 x - 18

x ((x - 4) (x - 1))

sin (x) (\frac{π}{2} - x)

p (1, - 1) q (4, 1)

\frac{3 ( 15 - 5 )}{10}

\frac{2 x + 1}{x ( x ^{2} - 1 )}
